Ueli Steck is one of the best-known mountaineers of our time, made famous by his many achievements, including first ascents in the Himalaya and most notably his record-shattering speed ascent of the north face of Switzerland’s Eiger in 2008. (The excellent film The Swiss Machine chronicles Steck’s quest for the Eiger record; a trailer for the film can be seen here.) In this video, he explains his plans for future climbs, and climbs some breathtaking overhanging mixed terrain.
